Somehow the last hunk (rtd16xx.dtsi) didn't apply with git-am or patch
-p1, not sure why. I have manually copied the file into place and fixed
up some more nits below:

Order not fixed from v2. This is a schema violation and logically wrong.

Space missing before =. Missed that in v2.

The comments were intended to go above each node, not after the aliases.
I've taken the liberty to annotate them further with their PCB label.

If the node has a unit address, it also needs a reg property with that
value. So let's drop the unit address.

Now that they're in the same file, this can just go into the node.
